Description
RXP-X 260 STAGE 3 KIT
This kit delivers a significant level of performance (+10mph on U.S. models) through easy to install, bolt-on engine, exhaust, and pump enhancements. Requires use of fresh premium octane pump fuel (91~93).
RIVA Power Filter Kit is installed. Air intake is relocated forward away from hot engine delivering cold, fresh air to engine via large 4” smooth-bore ducting that is attached to supercharger with unique velocity stack and sturdy billet clamps.
RIVA Catch Can/Engine Breather Upgrade Kit is installed. Easy to install catch can/oil breather eliminates power-robbing crankcase fumes and oil vapor from your engine’s air intake. Increases horsepower by removing the engine’s requirement to burn relatively non-combustible oil. Also improves intercooler efficiency by preventing the oil sludge coating that lowers thermal efficiency.
RIVA/ViPEC V88R3 Pro-Series ECU is installed. Our racing ECU provides huge increases in performance and matches the needs of your modified engine. Base maps are calibrated to provide optimum fuel delivery, ignition timing and rev limit to compliment the Riva Racing Performance Kits. OEM dash display, engine diagnostics & engine safety functions are retained. This ECU also provides “First In – First Out” data logging. This internal data logging function continuously records engine data, overwriting oldest data when the memory is full. This ECU is fully programmable, allowing the user to adjust or create new parameters. Includes input for optional Lamda sensor kit for data logging air/fuel ratios & tuning functions. ECU plugs directly into OEM wire harness and mounts directly in place of the stock ECU.
RIVA Sea Doo XX-2 Charger. Our new XX2-Charger delivers 15 psi of boost pressure at 8,500rpm producing arm wrenching acceleration and increased top speed. High performance billet impeller & 4MM spacer increase horsepower through superior impeller blade design and larger interior housing volume. Lightweight billet impeller features a sophisticated blade design that is precision balanced to deliver smooth operation. Spacer & impeller install quickly and easily onto stock supercharger base plate.IJSBA Limited Class legal. Requires RIVA/Athena Pro-Series ECU, RIVA Pro-Series Fuel Injectors (100lb) & RIVA Fuel Pressure Regulator Kit for correct calibration. Includes detailed installation instructions.
RIVA Intake Manifold Upgrade Kit is installed. Removal of restrictive screen element from inside of intake manifold enables your engine to produce more horsepower through increased boost pressures (+1lb). Special o-ringed, billet block-off plug with integrated fitting for aftermarket boost pressure gauge fills opening left after removal of screen element.
RIVA Fuel Pressure Regulator Kit is installed. Kit provides precision control of fuel pressure to meet fuel requirements of modified engine. RIVA Stage 3 Kit requires a consistent fuel pressure of 58psi (static/non-rising rate). OEM fuel pressure varies between 48~58psi. Plugs directly into original fuel system with OEM connectors and features a large 3/8″ fuel return line. Includes integrated liquid-filled pressure gauge and billet Fuel Pressure Regulator Block-Off necessary for removal of stock fuel pressure regulator in fuel tank.
RIVA Pro-Series Fuel Injector Kit is installed. Our 100lb racing injectors flow more fuel to match the needs of our Stage 3 modifications.
RIVA Valve Train Upgrade Kit is installed. Titanium valve retainers and heavy-duty valve springs increase reliability of modified engine by recucing the possibility of valve float at high RPM. To ease installation of Valve Train Upgrade Kit we offer a unique Valve Compression Tool that allows installation without removal of cylinder head saving you time and money.
RIVA Free Flow Exhaust Kit is installed. Kit allows removal of restrictive sound suppression system located between waterbox and hull exit. Improves engine performance by reducing back pressure & restriction.
